The long-classified document detailing possible connections between the government of Saudi Arabia and the Sept. 11 terrorist plot released on Friday is a wide-ranging catalog of meetings and suspicious coincidences.

It details contacts between Saudi officials and some of the Sept. 11 hijackers, checks from Saudi royals to operatives in contact with the hijackers and the discovery of a telephone number in a Qaeda militant’s phone book that was traced to a corporation managing an Aspen, Colo., home of Prince Bandar bin Sultan, then the Saudi ambassador to Washington.

The document, 28 pages of a congressional inquiry into the Sept. 11, 2001, attacks, is also an unflattering portrayal of the kingdom’s efforts to thwart American attempts to combat Al Qaeda in the years before the attacks.

But it is also a frustrating time capsule, completed in late 2002 and kept secret for nearly 14 years out of concern that it might fray diplomatic relations between the United States and Saudi Arabia. Subsequent investigations into the terror attacks pursued the leads described in the document and found that many had no basis in fact. But the mythology surrounding the document grew with each year it remained classified.

The Obama administration sent a declassified version of the document, with some redactions, to the congressional leadership on Friday. Its release on the website of the House Intelligence Committee later in the day marked the end of a years-long fight by lawmakers and families of the Sept. 11 victims to make public any evidence that Saudi Arabia may have played a role in the attacks.
